HENRY VAUGHAN LANCHESTER AND FREDERICK \VILLIAM LANCHESTER, OF BALI-TAM, COUNTY OF SURREY, ENGLAND.

ADVERTISING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 415,872, dated November 26, 1889.

Application filed July 3, 1889.

To all whom it may concern:

Be it known that we, HENRY VAUGHAN LANOHESTER and FREDERICK WILLIAM LAN- CHESTER, subjects of the Queen of Great Britain and Ireland, and residing at Balham,

in the county of Surrey, England, have invented new and useful Improvements in Advertising Apparatus, of which the following is a specification.

This invention consists in apparatus by means of which advertisements are made to appear and disappear or to change color, or two advertisements or portions of an advertisement are made to appear alternately.

In the accompanying sheet of illustrative drawings, Figure 1 is an elevation of an apparatus constructed according to this invention, and in which the grating is fixed and the card is movable, and showing one position of the card. Fig. 2 is a similar view to Fig. 1, showing the other position of the card. Fig. 3 is a sectional plan of the same. Figs. 4 and 5 are similar views to Figs. 1 and 3, respectively, showing a similar apparatus in which reflecting-surfaces are formed on the bars of the grating to intensify the exhibited matter. Fig. 6 is an enlarged detail view showing the action of the reflecting-surface in intensifying the advertisement. Fig. 7 shows in partial elevation a convenient method of suspending the card so that it can be actuated by a vibratory movement. Fig. 8 shows in cross-section an arrangement in which the grating is arranged to slide on the card. Fig. 9 illustrates in cross-section an arrangement in which the card and grating are securely attached to one another and the required effect is produced by the relative movement of the observer and advertisement 40 as a whole.

With reference to Figs. 1, 2, and 3, the card 13 slides on a frame 0, which carries the grating A. The card B is shown in its two extreme positions in Figs. 1 and 2, and represents parts of the words Patent Advertiser. At the righ t-hand end the grating is broken away, showing the form in which the lettering is represented on the screen by the n of Patent and is of Advertiser.

$erial No. 316,420- (No model.)

\Vith reference to Figs. 4, 5, and 6, the grating A is shown stamped from sheet metal, the part removed in forming the slots being bent to form reflecting-surfaces. Fig. 4 shows the bot-tom part of the letter d, and Fig. 6 shows to an enlarged scale the action of these surfaces in reflecting light.

In Fig. 7 the card B is shown supported at its ends by links D, so that it will be in a state of equilibrium only in its extreme positions, and will alternately be thrown from one to the other by any vibration communicated to the frame 0.

In Fig. 8 the grating A is shown arranged to slide on the card B. It is obvious that the arrangements shown in Figs l, 5, 6, and 7 are equally applicable to this arrangement.

In Fig. 9 the card B is shown rigidly secured to the grating A, a space being left between them.

lVhat we claim, and desire to secure by Let- 7o ters Patent of the United States, is-

I. In an advertising device, the combination, with a grating formed of parallel bars, of a card supported behind said grating and bearing one or more advertisements formed of parallel bars corresponding in width with the width of the grating-bars and adapted to be hidden by said bars, each advertisement being separately visible through said grating, substantially as set forth.

2. In an advertising device, the combination, with a grating formed of parallel bars, of a card supported behind said grating and bearing one or more advertisements formed of parallel bars corresponding with the grating bars, each advertisement being separately visible through said grating, and reflecting-surfaces secured to the fronts of the grating-bars, substantially as set forth.

3. In an advertising device, the coinbination,with a grating formed of parallel bars, of a card arranged behind said grating and bearing one or more advertisements formed of parallel bars corresponding with the grating-bars, one of the said elements being adapted to slide laterally upon the other, whereby each advertisement is separately visible between the bars of the grating or of an advertisement-card sliding behind said hidden behindthem,snbstantia11yas setforth. In witness whereof we have hereunto set 4. In an advertising device, the coinbinao'urhands in the presence of two witnesses. IO tion, Wlth a gi'atlng formed of parallel bars, HENRY VAUGHAN LANOHESTER.

T I Y b grating and visible through its bars, and the FREDERICK HHAM LAMHESTER vertical links D, pointed at each end and piv- \Vitnesses: otally supporting the ends of the ea1*d, sub- V GERALD LAYTON SMITH, stantially as setforth. PERCY \VOODWARD.
